Problem using a Samsung 64gb sd card.
I just bought a Samsung GB sdcard, and I've reformatted it into FAT32. My butterfly can read it with no problem. I have problem after I copied my old files into this new card and put it into my X920d. On my computer, everything has been copied and the total usage is just the same. But when I put it into my phone, some files just missing, and you can see the space(usage) getting less, files lost. Any comment??
